In GIT you may finish with a bunch of escape characters (ESC) when invocating colors for “git log” and “git diff”.
ESC[31m- Oid res = InvalidOid;ESC[m
ESC[31m- Relation rel;ESC[m
ESC[31m- StringInfo buf;ESC[m
ESC[31m- char *storageName = NULL;ESC[m
ESC[31m- int prefix = 0;ESC[m
This is due to the default pager which is “less”, because it cannot interpret correctly the escape characters.
There are a couple of ways to avoid that.
The first one is to change the pager to “more”.
git config --global core.pager more
The second one is to append an additional command with “less -r”.
git diff --color | less -r
git log -p --color | less -r
And you get a nice colored output.
Here is another solution which is more portable to my mind, and it is the one I use.
git config --global core.pager "less -r"
This directly appends the modified less command when git pager is invocated to print correctly escape characters.
